Liebherr has unveiled its first battery powered crawler cranes – the 200-tonne capacity LR 1200.1 unplugged and the 250-tonne capacity LR 1250.1 unplugged.
Liebherr launched the cranes during an online presentation on December 1, 2020. The cranes – named unplugged due to their ability to operate without a cable – feature batteries that can be recharged from a jobsite’s electricity supply.
The capacity of the battery is designed for four hours of lifting operations.
Speaking of the product developments, Gerhard Frainer, managing director for sales at Liebherr-Werk Nenzing, said: “With our unplugged cranes we offer our customers an alternative drive design. As we have already seen with the LB 16 unplugged, the first battery-powered drilling rig, the strategy is a complete success. Strict requirements regarding environmental sustainability in tenders for construction projects increase the demand for advanced technologies. For us, it was clear that we extend and successfully establish the design in further product groups.”
During the presentation, the manufacturer also launched the HS 8070.1 – “the newest generation of duty cycle crawler cranes”, said Liebherr.
It has a lifting capacity of 70 tonnes and features a self-loading system, which allows it to be easily disassembled for transportation.
The boom of the HS 8070.1 is compatible with the HS 8100.1 so customers can use attachments that are suited to both machines. Instead of a single counterweight, the machine has a modular system.
Liebherr described the machine as an “all-rounder”, suitable for a number of applications including material handling, deep foundation work, or lifting work.
Liebherr also unveiled the LRB 23 drilling rig, designed for deep foundation work.
